Feature Description

Removes the common part of two or more objects while merging other parts into a single object.

During XOR operations, various scenarios may occur. The following sections explain these scenarios in detail.

• If the participating objects intersect only at points, these polygon objects will be merged into a complex object (e.g., generating a complex polygon object with two sub-objects as shown below).
• If the participating objects intersect only along lines, their adjacent edges will disappear and merge into a simple object.
• If the participating objects intersect pairwise on surfaces without overlapping, their intersecting portions will be deleted and merged into a complex object (e.g., generating a complex polygon object with two sub-objects as shown below).
• If the participating objects consecutively intersect on surfaces without pairwise intersections (i.e., no common intersecting areas), they will merge into a simple polygon object.
• If the participating objects completely overlap, all objects involved in the operation will be deleted.
• If the participating objects are mutually non-intersecting, a complex object will be generated (e.g., generating a complex polygon object with two sub-objects as shown below).

Feature Entry

• Features Tab->Feature Editing Group->XOR.

Steps

1. With the layer editable, select two or multiple objects.
2. In the Features tab's Feature Editing group Gallery control, click the XOR button to open the XOR dialog box.
3. In the dialog box, specify objects to retain. For descriptions of the attribute processing dialog and its parameters after XOR operations, see Attribute Processing Dialog Description.
4. Click OK to complete the XOR operation.
